Early Demotic

Early Demotic (often referred to by the German term Frühdemotisch) developed in Lower Egypt during the later part of the Twenty-fifth Dynasty, particularly found on steles from the Serapeum of Saqqara. It is generally dated between 650 and 400 BC, as most texts written in Early Demotic are dated to the Twenty-sixth Dynasty and the subsequent rule as a satrapy of the Achaemenid Empire, which was known as the Twenty-seventh Dynasty. After the reunification of Egypt under Psamtik I, Demotic replaced Abnormal Hieratic in Upper Egypt, particularly during the reign of Amasis II, when it became the official administrative and legal script. During this period, Demotic was used only for administrative, legal, and commercial texts, while hieroglyphs and hieratic were reserved for religious texts and literature.

Middle (Ptolemaic) Demotic

Middle Demotic (c. 400–30 BC) is the stage of writing used during the Ptolemaic Kingdom. From the 4th century BC onwards, Demotic held a higher status, as may be seen from its increasing use for literary and religious texts. By the end of the 3rd century BC, Koine Greek was more important, as it was the administrative language of the country; Demotic contracts lost most of their legal force unless there was a note in Greek of being registered with the authorities.

Late (Roman) Demotic

From the beginning of Roman rule of Egypt, Demotic was progressively less used in public life. There are, however, a number of literary texts written in Late Demotic (c. 30 BC – 452 AD), especially from the 1st and 2nd centuries AD, though the quantity of all Demotic texts decreased rapidly towards the end of the second century. In contrast to the way Latin eliminated languages in the western part of the Empire, Greek did not replace Demotic entirely.^[2] After that, Demotic was only used for a few ostraca, subscriptions to Greek texts, mummy labels, and graffiti. The last dated example of the Demotic script is a graffito on the walls of the temple of Isis at Philae, dated to December 12, 452. The text simply reads "Petise, son of Petosiris"; who Petise was is unknown.^[3]

Uniliteral signs and transliteration

Like its hieroglyphic predecessor script, Demotic possessed a set of "uniliteral" or "alphabetical" signs that could be used to represent individual phonemes. These are the most common signs in Demotic, making up between one third and one half of all signs in any given text; foreign words are also almost exclusively written with these signs.^[4] Later (Roman Period) texts used these signs even more frequently.^[5]

The table below gives a list of such uniliteral signs along with their conventional transcription, their hieroglyphic origin, the Coptic letters derived from them, and notes on usage.^[4][5][6]
